This bug was moving very quickly across our cement patio to our bermuda grass lawn about 8:30 am, April 23, 2009. It has a very round back and head. It is mottled black with yellow, head is solid yellow; underbelly is shiny black. It appeared to be climbing stalks of grass, possibly nibbling on the ends; it tumbled off the stalks often, moving on to other pieces of grass. It moved almost too quickly to get a clear photo.
